CAR-WHEEL.

' SPECIFICATION formingpart of Letters Patent N 0. 416,637, datedDecember 3, 1889.

Application filed March 11,1889. Serial No. 302,752. (No model.)

Be it known that we, TIMOTHY MORRISSEY and JOHN DOYLE, citizens of theUnited States, residing at Ionia, in the county of Ionia and State ofMichigan, have invented certain new and useful Improvements inCarlVheels, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to new and useful improvements in theconstruction of metal wheels, especially of that class designed to beused on hand-cars, railways, velocipedes, and trucksof various kinds,and in pulleys in which lightness combined with requisite strength isthe main consideration.

To this end the invention consists in a peculiarly-constructedwheel-body, and in the means for securing the same to the tire and tothe hub of the wheel, all as more fully described, and shown in theaccompanying drawings, in Which Figure 1 is an elevation of a car-wheelembodying our improvement. Fig. 2 is a vertical central section thereofon line 00 min Fig. 1. Fig. 3 is a similar section with somemodification in the manner of securing the wheel-body. Fig. 4 is anelevation of the wheel-body detached, and Fig. 5 is an elevation of theinner face of one of the parts of the hub.

A is a rim of the wheel, made of cast-iron or steel, or of wrought-iron,as deemed most desirable for the purpose.

B is the body of the wheel, consisting of a single disk, preferably ofsteel-plate, formed with alternately raised and depressed segment-shapedpanels 0 and O, radiating from the center to the circumference of thedisk, with a plain margin D around the outer edge of the disk, and withthe radial panels C and C.

E are circular segmental flanges, formed on the outer edge of the diskby bending a portion thereof alternately upon opposite sides of thedisk. 7

F is a rim of the wheel which, for the heavier kinds of wheels, ispreferably formed with an inwardly-projecting flange G, integrallyformed therewith, as shown in Fig. 3. For the lighter classes of wheelswe prefer to construct the rim without said flange, as shown in Fig. 2,and the disk is secured to the rim by riveting the flanges'E directly tothe rim of the wheel, or to the flange G formed 5 5 thereon. The hub isconstructed in two parts, H and I, with the axle-box J preferablyintegrally formed with one of theparts, and these parts'are shaped upontheir meeting faces to represent an exact counterpart of that portion ofthe wheel-body extending into the hub, so thatwhen the parts are securedto-' gether, either by suitablebolts or rivets K, as

in Fig. 2, or by means of a nut L, secured on the axle-box, a solid hubis formed.

The parts being constructed as shown and described, we consider it thebest way of manufacturing to first out the required size of the diskfrom boiler-plate, with the portions forming the securing-flanges 6divided by radial cuts, then heating the disk thus prepared in asuitable furnace, and then shaping it at one operation between suitabledies.

By extending the inner ends of the panels into the hub of the wheel theparts of the hub, in order to fit the disk, will be provided withalternate wedge-shaped projections m and notches 01 upon one of theparts, and with corresponding notches and projections on the other part,and thus when the hub is secured to the disk a stronger lock will beformed between the parts in the radial lines of the wheel. The panelingstiifens the disk against compression in the radial lines of the wheeland against lateral deflection in the direction of the axle of thewheel, and, to get the greatest benefit therefrom, the number of panelsought to be correspondingly large.

While we have described our invention as particularly relating to theconstruction of car-wheels of the lighter description, it is obviousthat our improvement is applicable to the construction of other classesof wheels, and to pulleys as well, in which case they would preferablybe made in two sections, the sheet metal being bolted together at themeeting edges.

\Vhat we claim as our invention is 1. In a metal wheel, a wheel-body0011- structed of a sheet-metal disk pressed or indented with segmentalpanels in the radial direction of the wheel and projecting alternatelyupon opposite sides of the same, with portions between said panelsunindented and extending straight from the center to the rim,substantiaily as shown and described.

2. In a metal wheel, a wheelbody contructed of a single disk ofsheet-metal plate, with segmental panels indented into said body in theradial direction of the wheel and projecting alternately upon oppositesides of the same, with portions between said panels unindented andextending straight from the center to the rim, said sheet terminating toproject into the hub, substantially as shown and described.

3. In a metal wheel, a wheelbody constructed of a single disk ofsheet-metal plate, with the segmental panels C and C radially indentedinto the wheel, alternately upon 0pposite sides, and the segmentalflanges E, integrally formed therewith and alternately projecting uponopposite sides, substantially as described.

4:. In a metal wheel, the combination, with a Wheel-body constructed ofa single disk of sheet metal and radially indented to formsegmental-shaped panels projecting on opposite sides of the wheel andextending into the hub of the wheel, of a hub constructed in two partsand with their inner faces to form a counterpart of the correspondingpart of the wheel-body, substantially as described.

5. As a new article of manufacture, a carwheel consisting of the rim F,the body formed of a single disk of sheet metal, with thesegmental-shaped panels 0 and O, and the plain marginal portions D, thesegmental flanges E, alternately projecting upon opposite sides andriveted to the rim of the wheel, the hub constructed in two parts H andI, with the body of the wheel clamped between them and formed upon theirmeeting faces to lit the indentations of the body of the wheel extendinginto it, substantially as described.

6. In a metal wheel, a wheel-body constructed of radially-corrugatedsheet metal, having the plain circumferential margin D and flanges E,alternately projecting upon opposite sides, substantially as described.

In testimony whereof we affix our signatures, in presence of twowitnesses, this 4th day of February, 1889.
